so,
my check engine light has been on forever,
and i got the code,
it was my o2 sensor so i bought a new one,
and i can get the old one out,
i've tried letting it cool down,
trying right after running engine for a while [while hot]
every spray i could find,
and wrench to get best leverage...
this ting won't come out,
and it's starting to strip from me trying...
any tips on getting old o2 sensors out of civics?
[it's a '95]

 

Have you already tried using a special O2 sensor socket, which is available at auto parts stores?

 

yeah...
and the socket broke on it...

 

Sounds like you need a better quality O2 sensor socket and a good 24" breaker bar.

Edit: Return the poor quality broken socket for a refund.

 

yea you need more leverage

 

haha,
well,
kinda nubish question,
but where can i get a breaker bar?
i don't think i need the socket because i took the heat guard on my exhaust manifold so i can reach it without any "special" sockets

 

you need the special socket because it has a slit in it to allow for the wire to pass through it

 

Did you cut the top of the old sensor off to be able to place a socket over it? Either way, use a high quality 1/2" socket and a breaker bar. You can get a breaker bar from your local auto parts store.

 

but, if i can reach it with a regular wrench,
would that work too?
i really just don't wanna spend more money on this little part...

 

No, if you use a socket to remove it, you need the special tool. otherwise, you remove it while the mani is hot so the metal has expanded. and just use a short piece of scrap pipe and attach it to your wrench or ratchet. This is a breaker bar:
